The Reflex N 600 diaphragm expansion vessel is designed for sealed heating and cold water systems, providing reliable pressure control in closed-system installations.

Zilmet Hydro-Pro Vertical Expansion Vessel - 10 Bar. - 600Ltr Zilmet HYDRO‑PRO pressure vessels are designed for potable water and booster systems where stable pressure and efficient pump.

Built for sealed heating (EN 12828) and chilled-water systems, Flexcon Premium Expansion Vessels stabilise system pressure by absorbing thermal expansion so plant runs safely and efficiently.

A new TPO (thermoplastic polyolefin) diaphragm on 1235 Ltrs models delivers high flexibility and extremely low permeability, helping the pre-charge hold for longer. Lighter construction cuts material use and transport emissions; packaging is FSC-certified to reduce CO₂ impact.

• Sustainable design lighter TPO membrane uses up to 50% less material
• Long service life 15-year warranty
• Low permeability pre-charge pressure maintained for longer
• Heating & cooling suitable for LPHW and CHW installations

Vessels comply with EN 13831 and the Pressure Equipment Directive 2014/68/EU. Red epoxy powder coating (RAL 3002). Flexcon Premium 3580 are supplied with feet and a mounting kit.

Grundfos GT-D are maintenance-free double-diaphragm pressure tanks with a capacity ranging from 100 to 450 litres.
The tanks are designed for a maximum operating pressure of 10 bar and a maximum liquid temperature of 90 °C.

The tank is a steel pressure tank with a patented controlled-action CAD-2 diaphragm assembly, pre-charged to 1.4 bar. The tanks have a non-replaceable, chlorine-resistant 100 % butyl diaphragm with a precision-moulded copolymer polypropylene liner for superior air and water separation. The diaphragm assembly seals water in a truly non-corrosive chamber, while the air chamber is sealed with a fixed O-ring and closed cell foam, which provides long-lasting and service-free durability.

The tank is appropriate for drinking-water applications in combination with installations with booster systems, well systems, irrigation systems, thermal expansion, hydronic heating expansion, hydraulic hammer arresting and clean water backwash for ultra-filtration systems. The tank also features:

Product name: GT-U-600, vertical, PN 16

GT-U-600 PN 10 G11/2 V (coated flange)

Grundfos GT-U are bladder pressure tanks with a capacity ranging from 8 to 3000 litres. The tanks are designed for a maximum operating pressure between 10, 16 and 25 bar and a maximum liquid temperature of 70 °C. The tanks are approved for drinking water.

The tanks are steel pressure tanks, with non-toxic butyl rubber bladder enclosed by compressed nitrogen.

A pressure tank ensures controlled pressure in the water supply and thereby limits the switching frequency of the pump unit in case of low water consumption or loss due to leakage. This ensures increased comfort in your installation by limiting the start and stop frequency of your pump. It also creates a more stable assembly by compensating for pressure drops when a tap is opened, while reducing problems with water hammer in the pipes.

The Refix DE 600 diaphragm expansion vessel is designed for water supply installations that are not subject to DIN 1988 requirements, making it suitable for specialist systems such as fire extinguishing installations, service water systems
